Per developer info, the new builds of macOS 10.13.2 are 17C205 & 17C2205 - I'm assuming the latter is for the iMac Pro. iOS 11.2.2 build is 15C202. (Not sure why they didn't make the Safari updates v11.0.3.)

FYI on Nvidia Web Driver Updates:
New OS updates (versions or later build numbers after Security Updates) usually break any currently installed Nvidia web graphics driver. I'd switch to the default Apple driver and reboot before updating, if your card is supported with the default drivers. If not, wait for a Nvidia driver update. (Some non-Mac EFI cards are not supported by default macOS drivers.)
Of course have a current backup (and if possible, a Clone) of your boot drive before any update. I'll post Nvidia download page(s) for any updates when spotted.
Update: See the Jan. 10th news page for Nvidia Web Driver Update for macOS 10.13.2 (17C205). If you try the .104 driver with the new macOS 10.13.2 build, let me know if you see any pros or cons (especially any MacBook Pros with Nvidia GPU) - news at xlr8yourmac.com. (Please include mac and nvidia card details. Thanks!)

Saw some posts that the 10.13.2 Supplemental Update took a long time to complete the install.
(Some noted over 40min, others much less and some thought the update had hung.)
A reader replied:

"My 2013 Mac Pro took way longer to install (about 20 minutes) than my early 2008 Mac Pro (about 4 minutes). (Assume you used some tricks (patcher? or cloned copy?) to install 10.13 on the 2008.) Also on restart the 2008 sign in screen showed user name and password as both are set up to do in System Preferences, but the 2013 only had the password. As an aside the download rate was 7 times faster on the 2008 than the 2013, although that may not mean much (5MB/s to 35MB/s).

Thanks Richard. Posts in Apple's forum often noted much different times on various macs (same owner in many cases). My first thought was perhaps server load plays a part but maybe not.
